To provide the radiologist with a practical approach in order to differentiate urgent EVAR complications from deferrable complications.
AAA is a focal dilatation of the abdominal aorta,
exceeding the normal diameter of the vessel with 50% or larger than 3 cm of the vessel’s maximum diameter.
This pathological condition affects 2-8% of men and 1-2% of women and is therefore to be recognized as highly relevant (1-2).
The main and most fatal complication related to AAA is rupture of the aorta.
The mortality rate is high both in case of absence of surgery (85-90%) as well as when urgent surgery is performed (50-70%)....
Findings and procedure details
Computed Tomography Angiography (CTA) is the gold standard in the preoperative assessment and in the follow-up of AAA.
According to our clinical experience we recommend the acquisition of an unenhanced phase,
followed by an arterial phase performed with the aid of “bolus tracking” technique.
The venous/delayed phase is to be performed in all cases before EVAR procedure and during the first follow-up; subsequently only in few selected cases.
To simplify the discussion we decided to...
The radiologist's capacity to differentiate an urgent complication from a deferrable one facilitates the correct clinical-therapeutic follow-up of the patient.
